you need a lot staff in a movie it takes lots of people to make a movie so like around 70 .
It depends on how many are needed based on the size of the production and script.
A movie poster could include the following... Title age rating humour images slogan when its released star rating quotes producers who's in itand there is probly more but that would make a nice movie...
